Shockwave Therapy in Spokane Valley
Shockwave therapy — also called Extracorporeal Shockwave Therapy or ESWT — uses focused acoustic waves to stimulate the body's healing response in chronic soft-tissue conditions. Synergy Healthcare offers shockwave therapy using the StemWave acoustic-wave system as a non-invasive option for patients with persistent musculoskeletal pain that hasn't fully responded to standard conservative care.
What StemWave (Shockwave Therapy) Is
Shockwave therapy delivers high-energy acoustic waves to a targeted treatment area through a handheld applicator. The waves penetrate the skin and travel into the affected soft tissue, where research suggests they work through mechanotransduction — the conversion of mechanical pressure into cellular signaling that supports local circulation, reduces inflammatory mediators, and promotes tissue remodeling over time.
The technique has been used in medicine since the 1980s. It was originally developed for breaking up kidney stones (lithotripsy) and was later adapted for orthopedic applications. The system used at Synergy is the StemWave focused acoustic-wave device.
What the evidence supports
Different shockwave devices, intensity ranges, and protocols have different evidence bases. Looking at the published literature on focused shockwave therapy as a category, the strongest evidence is for:
- Chronic plantar fasciitis — supported by multiple randomized controlled trials and meta-analyses for cases that have failed initial conservative care
- Calcific tendinitis of the rotator cuff — strong evidence, particularly for the calcific component
- Lateral epicondylitis (tennis elbow) — moderate evidence for chronic, recalcitrant cases
- Achilles tendinopathy — moderate evidence for chronic, mid-portion or insertional cases
- Patellar tendinopathy (“jumper’s knee”) — moderate evidence for chronic cases
- Greater trochanteric pain syndrome — emerging evidence
- Non-union and delayed-union fractures — clinical evidence in specific contexts
Evidence is weaker and less consistent for broader applications — generalized chronic back pain, joint arthritis, or “any pain anywhere.” We’re upfront about that. Shockwave therapy is most useful when matched to a condition the published evidence actually supports.

Commonly Used Therapies:
What a Session Looks Like
Each treatment session lasts 10–15 minutes. The therapist applies ultrasound gel to the treatment area and positions the StemWave applicator over the target tissue. You’ll feel rhythmic pressure pulses during the treatment — most patients describe it as moderately intense but tolerable. Intensity is adjustable. No anesthesia or numbing is required.
Many patients feel some change after the first session — typically reduced muscle tension or improved pain, sometimes mild post-treatment soreness. The clinical effect tends to build across a treatment series; meaningful gains are most often seen between sessions 3 and 6.
The standard care plan is 10 sessions: twice weekly for the first 2 weeks, then weekly for 4–6 weeks, with the final 2 sessions spaced 2 weeks apart. Consistent scheduling matters — the protocol is designed as a complete series.
Who shockwave therapy is for
This is most useful for patients who:
- Have a chronic tendinopathy or connective-tissue condition that has persisted past expected healing time (typically 3+ months)
- Have tried initial conservative treatment — physical therapy, activity modification, anti-inflammatory medication, bracing — without full resolution
- Want a non-invasive, drug-free option to consider before moving to corticosteroid injection, PRP, or surgery
- Have been screened for contraindications (listed below)
It is not the right starting point for acute injury, for pain that hasn’t been clinically evaluated, or for chronic pain with a clear non-mechanical cause. We assess each patient individually before recommending shockwave therapy.
